Product DetailsX-Bionic APANI Merino Fastflow Women's Running Tights Wool is not smart. It only warms by nature. For the first time, X-Technology Swiss make wool smart by implementing numerous,sophisticated technologies like the 3D Bionic Sphere System. APANI MERINO - as pure as nature intended - naturally cools, warms and dries where necessary and not just where it can. The result is an ecological product, which is developed, designed and manufactured in Europe. The fine yarn, which is spun in Germany, is made from Saxon-Merino wool with a diameter of 18.5 micrometers containing an elastic and natural component. This combination guarantees the highest degree of form stability and wearing comfort.The tights are constructed with a Two-Step 3D BionicSphere System which is a high-tech knitting technology which ensures optimal grip and climate comfort. The different ribs and surface constructions support and transport moisture as well as warmth. The sweat of the lower back area is conducted through the 3D Bionic Sphere System to the tailbone for evaporation. The SweatTraps on the lower back are targeted specifically at catching sweat flowing towards the buttocks. This first phase, which often leads to friction sores, is interrupted before it can even begin. Fitted with ISO-Pad which targets insulation of individual body parts against ambient coldness can prevent the body from getting cold. This is why ISO-Pads over the hipbones retain body heat that is necessary to guarantee interior organ functionality. For added comfort and warmth, the Expansion Knee improves its insulating character rather than losing it when the knee is bent. A highly flexible system of chambers and channels provide insulation by storing warm air inside. Located around the waistband and calfs is Aktiv-Bund which provides highly elasticated cuffs which ensure a perfect fit without constricting. The tights are constructed with ISO-Base which is located on the back of the tights as when the body moves, the pants are stretched over the seat area when sitting body weight pushes the material together. In both of these situations, cold bridges can occur. The anatomically formed ISO-Base has special air channels that trap body heat and prevent the large gluteal muscles from undercooling. To keep the wearer feeling cool and comfortable, the tights are equipped with the Air Conditioning Sport which located at the back of the knee. The knee hollow perspires quickly and heavily so a fine, circular knitted fabric has been incorporated there. Perspiration dissipates and is pushed outward with the body of body warmth without the risk of chilling.FeaturesTwo-Step 3D Bionic Sphere System - Ensures optimal grip and climate comfort.
